Driving and Operating leave just enough slack so the combination can turn. Never allow safety chains to drag on the ground. . 9-107 Trailer Brakes A loaded trailer that weighs more than 900 kg (2,000 lbs) needs to have its own brake system that is adequate for the weight of the trailer. Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. If the vehicle is equipped with StabiliTrak, the trailer cannot tap into the vehicle's hydraulic brake system. The trailer brake system can tap into the vehicle's hydraulic brake system only if: . The trailer's brake system will use less than 0.3 cc (0.02 cubic inch) of fluid from the vehicle's master cylinder. Otherwise, both braking systems will not work well or at all. If everything checks out this far, make the brake tap at the port on the master cylinder that sends the fluid to the rear brakes. Use only steel brake tubing to make the tap. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not use equipment that exceeds the maximum amperage rating for the auxiliary battery provision. Trailer Wiring Harness The vehicle is equipped with one of the following wiring harnesses for towing a trailer or hauling a slide-in camper. Basic Trailer Wiring All regular, extended cab and crew cab pickups have a seven‐wire trailer towing harness. For vehicles not equipped with heavy duty trailering, the harness is secured to the vehicle's frame behind the spare tire mount. The harness requires the installation of a trailer connector, which is available through your dealer. Auxiliary Battery The auxiliary battery provision can be used to supply electrical power to additional equipment that may be added, such as a slide-in camper. If the vehicle has this provision, this relay will be located on the driver side of the vehicle, next to the underhood electrical center. Be sure to follow the proper installation instructions included with any electrical equipment that is installed. The trailer parts can withstand 20 650 kPa (3,000 psi) of pressure.
